This kind of extrapolation of one variable over many decades, without accounting for any other societal, economic, or technological variables which may change, is simply not realistic.

And you don't know if they have accounted for such, but I can tell you they have had discussions on that. You are just talking out your crawl space.

China was allowed to barrel on, and had little limits put on its use of coal. Most of the semi-permanent particles come from US and Euro stack though. What was a revelation is that at some point we lose the Gulf Stream, and when we do, many areas on the eastern US coastline rise 3 feet rather rapidly. Whoda thunk?

I've been resigned for some time that we are going to conduct the great experiment and find out what man made climate change is like, but I've always put health care over climate change. As long as we can't really stop the change we might as well have good health care. Take a page from the Nordic side and we form US Inc., We make a buck off the assets we have left instead of giving them to fat capitalists to develop at below basement floor prices. We want a cut - for our healthcare, just like Norway has Equinor. Might as well get some decent health care out of the coming climate change. :)
